Juniper Networks Manager

About

The Juniper Networks Manager is an SNMP-based connector used to monitor and configure Juniper Networks devices. It also uses an SSH connection to change the interface state of some ports and to perform backup, restore, and firmware upgrade operations.

Some devices have large tables, so polling can be disabled for specific tables to limit unnecessary load.

Configuration

Connections

SNMP Connection

This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device, e.g., 10.11.12.13.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string used when reading values from the device (default: public).
  • Set community string: The community string used when setting values on the device (default: private).

SSH Connection

For its SSH connection, the connector requires the following input during element creation:

  • IP address: The polling IP of the device, e.g., 10.11.12.13.
  • Port number: The SSH port of the connected device, by default 23 or 22 (version 1.0.3.x).

HTTP Connection [1.0.10.x]

From version 1.0.10.x onwards, an HTTP connection is available, which requires the following input during element creation:

HTTP CONNECTION:

  • IP address/host: The polling IP or URL of the device.
  • IP port: The IP port of the device. Default: 3000. Note that for HTTPS, the default configured Juniper port is 3443, so this will have to be updated in the element settings.

Initialization

For SSH and HTTP communication, credentials must be configured on the Element Settings page of the element.

By default, all tables are polled. To reduce polling:

  • On the General page, open the Redundancy Table subpage and set Poll Redundancy Table to Disabled.
  • On the General page, open the Operating Table subpage and set Poll Operating Table to Disabled.
  • On the Interface Stats page, set Poll Optional Interface Stats to Disabled to stop polling the following columns: IF Type, IF Protocol Error, IF Discontinuity, IF Link Traps, IF Promiscuous Mode, IF Connector, and IF Speed.

Version range 1.0.2.x includes additional polling and measurement controls:

  • Polling Config (General page): The Polling Configuration Table allows you to configure the polling speed per table. Setting PCT - Polling Time to disabled (-1) stops polling for those parameters. A Refresh button allows manual polling. In range 1.0.9.x, each row has an individual toggle button and defaults to a 5-minute polling interval when enabled.

  • Measurement Config (Interfaces page): The Measurement Configuration Table allows you to disable individual interfaces to remove them from polling and from all interface tables. The Enable/Disable Interface [Description Filter] field enables or disables interfaces in bulk based on a string match. The Disable All, Enable All, and Enable Oper. Up buttons also allow bulk actions. The MCT - Filter Table (via right-click to add entries) auto-enables matched interfaces and disables all others; manual editing of the Measurement Configuration Table is only available when this filter table is empty.

Version range 3.0.0.x adds the following to the Polling Configuration Table:

  • A Lock State column (Locked/Unlocked) that prevents changes to polling time, polling state, and the Refresh button when locked. Locked rows are displayed in dark gray. Locking and unlocking can be applied via the right-click context menu.
  • When Real-Time Performance Monitoring: Ping Results is disabled, no action is taken on the row. If dependent tables are enabled, the row is automatically re-enabled and a message is shown.

Web Interface

The web interface is only accessible when the client machine has network access to the product.

How to Use

General Page

This page displays general device information including System Name, System Uptime, CPU Usage, and Memory Usage.

Page buttons provide access to:

  • Redundancy Table: Displays redundancy status. Polling can be disabled.
  • Services: Displays OSI layer status (Physical, Network, etc.).
  • Operating Table: Displays hardware information. Polling can be disabled.
  • Conditional Monitoring: Parameters for importing and exporting files.
  • Storage Table: Displays storage utilization.
  • TCP/UDP Stats: TCP/UDP statistics including TCP Connection Table and UDP Listener Information.
  • ICMP Stats: ICMP statistics such as ICMP Received Messages and ICMP Sent Echo Reply.
  • IP Stats: IP statistics such as IP Forwarding and IP Datagrams Received.

Prior to range 1.0.2.x, input fields in the lower-right corner allow the importing or exporting of current values to a file.

Interface Stats Page

This page displays Interface Statistics. The IF State Custom Change column allows you to force the state of ge or xe type interfaces to up or down. This is applied when the Commit IF Changes button is clicked.

The More Stats page button opens the More Interface Stats page, which contains two tables: More IN Interface Stats (IN Octets, IN Ucast Pck 32, etc.) and More Interface Stats OUT (OUT Errors 32, Out Mcast Pck, etc.). Polling can be disabled for one or both tables.

In range 1.0.3.x, the Measurement Configuration page button is also available here.

RSVP-MPLS Page

This page displays the RSVP Session Table, along with standalone parameters for Active LSP Ingress, Transit, and Egress.

DOM Page

This page displays Digital Optical Monitoring data. From range 1.0.6.x onwards, power data is converted to the appropriate units (mA, dBm).

RPM Metrics Page [1.0.3.x]

This page displays RPM (Real-Time Performance Monitoring) metrics including RTT (minimum, maximum, average, and standard deviation round-trip time) and sent/received probe counts and percentages between network nodes.

The Description column in all tables on the RPM Metrics, Ping Probe, and RPM History pages is based on the Ping Results Table (ID 24000 in Ping Probe).

Ping Function Page

This page displays parameters to configure and retrieve statistics for the Ping Functionality.

Element Settings Page

On this page, you can configure the HTTP and SSH credentials used for HTTP polling and SSH connections, as well as run SSH commands to back up, restore, or upgrade the device.

Backup / Restore

  • Backup: The Backup File Name is copied via SCP from the Backup Device Directory to the Backup Remote Directory.

    Example: scp /config/juniper.gz user@10.10.132.18:~/juniper.conf.gz

  • Restore: The Restore File Name is copied via SCP from the Restore Remote Directory to the Restore Device Directory, then committed to the device.

    Example: scp user@10.10.132.18:~/juniper.conf.gz /tmp/juniper.conf.gz

The Restore Timeout parameter configures how long to wait before the restore commit is considered timed out.

Firmware Upgrade

The Upgrade File Name is copied via SCP from the Upgrade Remote Directory to the Upgrade Device Directory. After the copy, a load override with validation is performed. When this is successful, the file is committed and the device reboots.

Example: scp user@192.168.10.1:~/jinstall-xxx.nnn-domestic-signed.tgz /tmp/

The Upgrade Timeout parameter configures how long to wait before the upgrade is considered timed out.

From version 1.0.3.7 onwards, a Software Rollback button is available.

Web Interface

This page accesses the device web interface. The client machine must have network access to the device.

DataMiner Connectivity Framework

The 1.0.5.x through 1.0.10.x ranges of the Juniper Networks Manager connector support the usage of DCF.

Interfaces

Dynamic Interfaces

Physical dynamic interfaces:

  • Interfaces from the Interface Stats table are exposed as physical dynamic interfaces of type inout.
